User Guide

SAP AG November 2002
If the user does not belong to a user group, the “Current User” is the user name they entered
to gain access to the database instance. If, on the other hand, the user does belong to a user
group, the “Current User” is name of the user group.

Database Trace
You can enable the writing of a database trace. In this case, the trace writer task [Page 16]
logs all reactions of the database kernel to database statements in the database trace. This
also means that the database trace can be used not only to trace errors that occur when
statements are processed but also to provide a more exact classification of inconsistencies
caused, for example, by hardware errors.
Only enable the writing of a database trace if you are asked to do so by the SAP
DB Support team. We do not recommend that you enable the database trace
function unless it is really necessary, because it seriously affects the performance
of the database instance.
If the writing of the database trace is enabled, you should be running the database instance
[Page 132] with the smallest load possible, and only those actions needed to reproduce the
error should be performed on the database instance.
Disable the writing of the database trace as soon as the actions needed for the analysis have
been logged.

Database User
Database users log on to a database instance [Page 132] and work with database objects
such as tables, views, and indexes (the SAP DB user class [Page 149] is database user).
SAP DB differentiates between various database user classes [Page 28].
